Avoid alcohol-containing gas treatment products when using E10 fuel.
Portable, reusable Ethanol Fuel Test Kits check presence of alcohol in all types of liquid.

All Fuel Additives & Fuel System Treatment Products, that contain alcohol, should be avoided or used with caution with E10 gasoline.

Learn the common and chemical names for ethanol and alcohols found in
many fuel system treatment products/additives.

List of Common and Chemical Names for Alcohols & Alcohol-Blends:

List of Chemical Names for Alcohol and Ethanol
Check if gas additive and fuel treatment products you use contain alcohol.
Check ingredients/alcohol content of gas additive and fuel treatment products.
Review Fuel Additive & Gas Treatment Products for alcohol - ethanol content.
View Marine Additive Products.

Carefully review ALL ingredients of all fuel treatment products before use.
More Information:

- Review the wording and letters of each ingredient listed before adding product to gas tank.

- Many alcohol (ethanol type) chemical names end in "ol".   E.G. ethan"ol", methan"ol".
- Sometimes the common name of alcohol based ingredients is not so obvious. 
E.G. Carbon disulfide = Alcohol Sulfuris, Aromatic Spirit of Ammonia  = Ammonia in alcohol.

- Review the MSDS (Material Safety Data Sheet) and check each ingredient before use.

- Sometimes manufacturers refuse to disclose ingredients. MSDS will state something like, "Proprietary or trade secret ingredient(s)". Examples = Startron, STP Octane Performance Booster.  Note: There are many other products that refuse to list all ingredients.
Only hazardous chemicals must be disclosed.

- Some fuel sytem products do not list alcohol in their ingredients, but instead may contain a chemical that has similar properties to ethanol.

- Desiccants, like alcohol, also have a strong affinity for moisture and will absorb relatively large amounts of water from the environment. Deliquescent salts include calcium chloride, magnesium chloride, zinc chloride, Carnallite and sodium hydroxide. 

- All fuel additives that are "hygroscopic" or "miscible" (attract and absorb or adsorb water) or have a drying effect should be avoided.

- Fuels and additives that contain ethanol will decrease efficiency and mpg.  More information.

- Several companies use deceptve marketing tactics, to convince customers that their "miracle" product will "prevent, fix repair and/or reverse" all ethanol-related fuel problems - No such miracle product exists!

- E85, FFV's and AFV's are designed to be compatible with alcohol blends of gas up to 85 % ethanol.

- Additives that increase the alcohol content of gas over 10% will invalidate most engine warranties -
(Check your engine's owners manual and warranty).

Gas Additives categories that most likely contain alcohol include:

Gasoline Water Removers - Fuel System Cleansers - Fuel Conditioners - Fuel Detergents - Fuel Stabilizers -  Rust Inhibitors - Octane Enhancers -

Alcohol Fuel Test Kits will check both gas and liquid gas additive products
for ethanol/alcohol content.
